Looking at Liana, the bootstrap works by compiling an older `rustc` with `mrustc` and then compiling newer `rustc` with the compiled older `rustc`, right? So technically it is bootstrappable.

So that means that there is a way to review the entire chain. Hopefully someone is also doing that.

Rust is an existential threat.

I only mention Core, because it uses the same bootstap chain, that you could use for LDK, LNDK, Ord, etc. Maybe it would have been better to mention Liana wallet, which is Rust-based and uses this bootstrap chain too.
